Crimson Trace Lasergrips provide a pinpoint accurate laser each time you naturally grip the firearm, no fumbling for switches or buttons. Installation can be done in a matter of minutes because Crimson Trace Lasergrips install exactly like factory grips. In the front activation models, Instant activation occurs due to pressure applied by your fingers to the switch located on the forward side of the grip. Equipped with a master On/Off switch, Crimson Trace Laser Grips save battery and allows use of the firearm without laser. Lasergrips produce a 1/2" red dot at 50 feet and are a class IIIa Diode Laser (Non-hazardous to eyes under momentary exposure).
